Abstract

DC60 (07/03/45) A throttle actuator for the internal combustion engine is provided for Setting the tongue opening rhythm and The valve closing timing for the intake valve is optimized in accordance with Operating conditions of the internal combustion engine In order to improve Fuel efficiency and power Of the internal combustion engine in order to eliminate fuel stagnation in the intake flaps and Sticking of The intake valve is attached to the tongue of the said valve and in order to reduce the cost and weight. Control the work of The valves control the on / off actuation of the exhaust flap (EV1, EV2) and the first and second intake flap (IV1, IV2) located in one cylinder (4). Electromagnet (5) opens / closes the first intake valve (IV1) using an electromagnet. The cam valve actuator mechanism (6) opens / closes the second intake valve (IV2) by means of the intake cam (11) positioned on the camshaft (10), driven in the same rhythm. With the rotation of the internal combustion engine (3) the trigger of the tongue. The cam type (6) can generate circulation in the cylinder within the cylinder combustion chamber (4). The ECU (2) controls the action of the operating mechanism. For the electromagnetic valve (5) and the cam actuator mechanism (6), the valve actuator for the internal combustion engine is provided for Setting the tongue opening rhythm and The valve closing timing for the intake valve is optimized in accordance with Working conditions of the internal combustion engine in order to improve Fuel efficiency and power Of the internal combustion engine in order to eliminate fuel stagnation in the intake throttle and Sticking of The intake valve is attached to the tongue of the said valve and in order to reduce the cost and weight. The valve actuator controls the on / off operation. Of the exhaust valves (EV1, EV2) and the first and second intake valves (IV1, IV2) located in one cylinder (4), the electromagnetic throttle actuator (5) opens. The first intake valve (IVI) is switched on / off by means of an electromagnet.The cam type valve actuation mechanism (6) opens / closes the second intake valve (IV2) using the integrated intake cam (11). On the camshaft (10), which has been driven in The same stroke as the internal combustion engine rotation (3), the cam actuator (6) can generate circulation in the cylinder under In the combustion chamber of the cylinder (4), the ECU (2) controls the electromagnetic actuation mechanism (5) and the actuation control mechanism. Cam-type tongue (6)
